Electronic design
Knowledge of components and how to use Eagle to design circuit schematics.

Eagle is a printed circuit board (PCB) design tools, including three modules,schematic editor, PCB editor and automatic routing device.We shoulf know what each component is and what it can do.Be very careful when connecting them,because I make a mistake to connect GND instead of VCC.That took a lot of time to solve.

Switch:
(Button Slide) Switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another.
Resistor:
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors may be used to reduce current flow, and, at the same time, may act to lower voltage levels within circuits.
Capacitor:
A capacitor is a passive two-terminal electrical component used to store electrical energy temporarily in an electric field. (bucket) Used to filter current.
Diode:
In electronics, a diode is a two-terminal electronic component that conducts primarily in one direction Anode (+) Cathode (-).
LED:(Light Emitting Diode).
Transistor:
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.
Crystal / Resonator:
Is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency. This frequency is commonly used to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers.
Regulator:
A voltage regulator is designed to automatically maintain a constant voltage level. Electronic voltage regulators are found in devices such as computer power supplies where they stabilize the DC voltages used by the processor and other elements.
Micro Controller:
A microcontroller (or MCU, short for microcontroller unit) is a small computer (SoC) on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals.
Sensors and actuators.

Then it can generate the PCB board and we shuould adjust its position. Then we can save as PNG,one is a trace and another to cut.Black means it will be removed,so we should conversion color by use another software such PS.
